Hello Mr. Mitchell, Thank you for your bug report. However, this is not a bug. Simply, there is no such thing is a preallocation of the threads. Thread cache works only after client-side created connection is closed. Let me cite you from our 5.6 Reference Manual: " To enable N inactive connection threads to be cached, set thread_cache_size to N at server startup or at runtime. A connection thread becomes inactive when the client connection with which it was associated terminates. " Not a bug.
